I am not sure how to modify the config.h script for my CentOS 4.5 box (running Nagios + NDOutils). NDOutils seem to compile fine (./configure && make), but I'm having problems when I try to run the final command in the README file. ********* problems *************************** ndo2db-2x -c /etc/nagios/ndo2db.cfg Support for the specified database server is either not yet supported, or was not found on your system. ************************************************ Someone else (http://tinyurl.com/2jnef8) suggested modding the config.h file in order to eliminate that command CHANGE #include <mysql/mysql.h> #include <mysql/errmsg.h> TO #include </usr/local/mysql/include/mysql/mysql.h> #include </usr/local/mysql/include/mysql/errmsg.h> However, when I looked for mysql.h (e.g. "locate mysql.h") I couldn't find find them (maybe b/c I installed from package?). What might I need to do in order to modify this script for CentOS so that ./configure will run properly and let me install this?
